Why do my teeth bleed for no reason
Bleeding usually comes from inflamed gum tissue or another oral site, rather than from the tooth itself.
The short answer
Teeth do not bleed, but the surrounding gingiva or another oral tissue may bleed because of inflammation, trauma, infection, medication effects, or a less common medical problem.
Where does unexplained bleeding around a tooth come from?
Bleeding usually comes from small blood vessels in inflamed gum tissue, not from the hard enamel or dentin of the tooth. Plaque, calculus, vigorous brushing, recession, a sharp appliance, and infection can make one area bleed.
How should I check and clean an unexplained bleeding site?
Use a soft brush and clean the gum margin and interdental spaces gently, then note where and when the blood appears. Do not stop all cleaning because plaque left at the margin can sustain inflammation.
When does unexplained mouth bleeding need prompt care?
Arrange prompt assessment for spontaneous or heavy bleeding, bruising elsewhere, fever, swelling, a persistent ulcer, or bleeding that does not settle with gentle pressure.
What should I ask about the source of oral bleeding?
Ask where the blood is coming from, whether gum probing or an X-ray is needed, and whether medicines or a medical condition could be affecting clotting.
